If you realie that your talk about subsetting the BCP47 was wrong, then we can
at least put that misunderstanding to the side ... :-D

The spec defines - in principle - how a unknown tag should be handled. But it
does not cover the issue that the 'unknown' or 'unreckonized' tag could be
recognized/known by some other registry or convention than the BCP 47 one, and
that the UA - or API - might know that convention. At least, that is how I read
it.

I read the screenreader example of the spec as more of an adhoc case.
